This indicator shows the chart of a required currency pair in the additional window. The indicators created with the use of the OnCalculate() function first form can be implemented to an additional chart.
It must be considered that synchronization failure between the time series of different currency
pairs is possible at short timeframes. Therefore, the indicators may be displayed incorrectly. The issue is described in the article "The Implementation of a Multi-currency Mode in MetaTrader 5". It is not recommended to add other indicators, if a chart timeframe is less than M5.
